Habitat Comparison
Emperor Penguin
Antarctic pack ice and surrounding Southern Ocean. The only penguin species that breeds during the Antarctic winter.
Shoebill
Freshwater swamps dominated by papyrus and other dense aquatic vegetation in tropical East Africa.
Song & Call Comparison
Emperor Penguin
Loud, resonant trumpeting calls used for individual recognition in dense colonies. Each bird's call is unique in frequency. Also gives softer contact 'braying' notes.
Shoebill
Largely silent; produces mechanical bill-clattering 'clap-clap-clap' when greeting at the nest — similar to White Stork. Also gives low croaking grunts. Rarely calls in the wild.
Geographic Range & Migration
Emperor Penguin

Black head, chin, and dorsal side with white belly. Bright yellow-orange ear patches fade to pale yellow on the upper breast.
Long, slightly decurved bill — black with orange or pink mandible stripe
Shoebill
Blue-grey plumage overall with a slightly darker back and wings. Powder down gives a washed-out appearance. Small tuft on the back of the head.
Massive shoe-shaped bill, one of the largest of any bird — pale yellowish-grey with darker markings
About These Birds
Emperor Penguin
体型最大、最重的企鹅。在南极冬季零下60摄氏度的环境中繁殖。雄鸟孵卵约65天，期间完全禁食。
Shoebill
The shoebill is one of the most sought-after birds for birdwatchers visiting Africa, prized for its prehistoric appearance and massive bill. It can stand motionless for hours before collapsing forward to seize prey in its enormous bill. Despite standing over a meter tall, shoebills weigh relatively little due to their hollow bones.
